Definitions
- the present invention relates to an image acquisition device of the patterns formed by the grooves of the skin of the fingers or the palm of the hand (commonly called fingerprints or palmar).
- a fingerprint identification comprises a step of acquiring an image of at least one fingerprint of the candidate for identification and a processing phase of this image to allow comparison with fingerprint images, or representations of these processed fingerprints to highlight the characteristics (representations called templates), stored in a database with the identity of the owner of each of them.
- Fingerprint identification techniques widely used in police investigations, tend to be used more and more for border control or for simple identity checks, for example when entering places. with restricted access like airports, companies ...
- the improvement of the processing methods combined with the increase in computing power of the computer means has made it possible to reduce the processing time which becomes negligible compared to the acquisition time, in particular when the identification requires the acquisition of images of several fingerprints (of several different fingers).
- the acquisition is generally performed by means of a device comprising a frame defining an acquisition zone extending substantially in a plane, an acquisition member which is fixed to the frame to have a sensitive face forming the acquisition zone and a processing unit connected to the acquisition member for processing a signal therefrom.
- the user applies a finger (or several fingers simultaneously or successively if necessary) against the sensitive face. This mode of operation is particularly slow and the finger must be immobile otherwise the acquisition of the digital fingerprint can not be made.
- the skin of the fingers is particularly dry and does not allow acquisition of sufficient quality to ensure good performance without waiting several tens of seconds.
- the finger contacts on the sensor foul it, which degrades the quality of the images and therefore requires periodic cleaning, and especially are perceived as unhygienic by users.
- An object of the invention is to provide acquisition means that is faster than current devices while having maximum ease of use.
- an image acquisition device of a fingerprint of at least a part of a user's hand comprising a frame defining an acquisition zone s' extending substantially in a plane, an acquisition optical element which is fixed to the frame to have a field covering the acquisition area, and a processing unit connected to the acquisition member for processing an image signal coming from this one.
- This device is characterized in that: - the frame is arranged to provide a zone of free space which contains the acquisition zone and which forms a passage for said part of the hand moving parallel to the plane,
- the device comprises a projection member of a luminous pattern of at least two colors in the acquisition zone, the optical member has a depth of field extending on either side of the acquisition zone; and has a color sensor having an acquisition speed sufficient to capture at least one color image of said portion of the moving hand at a predetermined maximum moving speed,
- the processing unit is arranged to extract from the color image signal a monochrome image in each of the projected colors, to reconstitute a texture of said portion of the hand from at least one of the monochrome images and a shape from at least one of the other monochrome images.
- This device allows a non-contact optical acquisition of a moving part of the hand, such as one or more fingers or the palm of the hand.
- the characteristics of the optical acquisition member ensure the obtaining of sharp images of the hand portion moving in the vicinity of the acquisition plane (the depth of the field allows a certain tolerance of positioning of the hand portion relative to at this level).
- the extraction of monochrome images from the color image signal makes it possible to have at least two images that have been taken simultaneously (the movement of the hand part would make it particularly difficult to automatically process several images taken successively) and which have different characteristics.
- this information concerns, for example, local deviations of the striations, the shape of the outlines of the striations, the position of the pores, nascent striations, the three-dimensional shape of the hand part .
- this information can extend to phalangin.
- This processing also makes it possible to obtain a predetermined resolution which simplifies the subsequent operations of comparison of the fingerprint images. It can thus be advantageously calculated a flown image of the fingerprint at a known resolution, producing an image comparable to traditional acquisition systems, but with an enlarged surface.
- the field of the optical acquisition member has a width sufficient for the acquisition area to cover several fingers of the same hand of 1 user.
- the processing module can thus be arranged to follow the fingers in the image series acquired, to segment them individually in 2D or 3D, to select the best representation of each finger in the sequence, or even to consolidate a set of representations of each finger.
- the processing module can be arranged to consolidate the images in order to obtain the 2D representation of the totality of the acquired palm surface and to reconstruct all of it. the form .
- the projection member is fixed to the frame so as to project the target towards a distal end of the fingers.
- the projection then generates little or no shadow carried by a finger on its neighbor, a shadow that could alter the image by reducing the amount of exploitable information for identification.
- it is generated from the texture image and the shape of the hand part a new unwrapped image, representing the image of the fingerprint at the same resolution in any point.
- the unwrapped image is identical to the image that would have been acquired with a system of acquisition by said coiled (systems where the finger is rolled on the acquisition surface to restore a complete image of the impression).
- the pattern comprises three colors with uniform illumination in one of the three colors and repetitive patterns in the other two colors and, advantageously, the uniform illumination is green and the repetitive patterns are red and blue.
- the green lighting reveals the texture of the impression in a particularly effective way.
- wavelength lights that are too large (red and infrared) are highly diffused inside the finger and provide a decreased contrast.
- a light of shorter wavelength (blue) poses problems of acquisition, since the cameras are less sensitive there.
- the usual color cameras have more green pixels than other colors, and this color is therefore preferable to reveal the high frequency information of the print.
- the repeating pattern is of a much longer period than the lines of the imprint so as not to introduce artifacts into the image of the imprint.
- the repetitive light patterns are crenellated or sinusoidal curves extending advantageously perpendicular to the direction of movement and having a non-zero angle with the target axis of the acquisition systems.
- This embodiment is particularly robust.
- the frame comprises a member for guiding the movement of the user's finger, which preferably comprises a translucent screen which extends on one side of the acquisition zone opposite to the optical member acquisition and which comprises at least one finger positioning mark and, advantageously, the device may further comprise an indicating element of a nominal speed of movement of the hand.
- the guide member helps the user to maintain his finger in the acquisition zone while moving it at a suitable speed with the acquisition capabilities of the optical acquisition unit.
- the device comprises a near infra-red lighting element and an infrared optical acquisition element is connected to the processing unit to transmit to it an infrared image signal and the processing unit is arranged to extract from the infrared image signal an infrared image showing a venous network of the finger.
- Near-infrared means wavelengths between 700 and 1000 nm. This makes it possible to detect a false finger that would be used by a fraudster and reproduce the fingerprint of another person but whose venous network does not correspond to that of the person whose finger was forged. In addition, the venous network can be used to confirm the result of an identification performed by the impression.
- FIG. 1 is a schematic perspective view of a device according to the invention
- FIG. 2 is a diagrammatic sectional view along plane II of FIG. 1,
- Figure 3 is a schematic sectional view along the plane III of Figure 1.
- the image acquisition device comprises a frame 1 comprising a desk 2 surmounted by a screen 3 which extends parallel to a transparent upper face 4 of the console 2.
- the upper face 4 and the screen 3 are inclined relative to the horizontal by an angle of approximately 45 ° so that the screen 3 is oriented towards a user who would face the desk 2.
- the upper face 4 and the screen 3 are spaced a distance of a few centimeters (for example five centimeters for the acquisition of fingerprints, and eight for that of the palms) to define between them an open space 5 open, here frontally and laterally on both sides, to form a passage for a hand of the user.
- the desk 2 contains two optical acquisition organs, namely a main optical acquisition unit, here a color camera, and an additional acquisition device, here an infrared camera 7, which are mounted in the desk 2 to have a field covering an acquisition zone 8 which is completely contained in the free space zone 5.
- the acquisition zone 8 is here more precisely in the center of the free space zone 5 and has a plane parallel to the
- the camera field ⁇ , 7 has a width sufficient for the acquisition zone 8 to cover several fingers of the same hand of the user (in this case, index, major, annular, auricular).
- the cameras 6 and 7 are set to have a field having a depth extending on either side of the acquisition zone 8.
- the cameras 6 and 7 have a sensor having a sufficiently high acquisition speed to take a image of a hand moving in the acquisition zone with a predetermined maximum speed of movement.
- the sensor used is for example a 1.3 million pixel sensor with a speed of between 60 and 100 images per second.
- Cameras 6 and 7 are connected to a unit of processing 9 to transmit therefrom color image signals and infrared image signals respectively.
- the processing unit 9 is here a computer executing an image processing program.
- the frame 1 also contains a projection member 10 of a luminous pattern in three colors.
- the projection member 10 is fixed to the frame below the path of passage of the fingers and is directed to the acquisition area 8 here covering the front of the fingers where the fingerprint information is the most discriminating.
- the pattern includes uniform illumination in one of the three colors, here in green, and repetitive patterns in the other two colors, here crenellated or sinusoidal curves in red and blue that extend perpendicular to the direction of motion from the hand.
- the pattern is set here to have an average finger-on period of 70 to 80 pixels at 740 dpi.
- the frame 1 also contains a projection member 14 of a near infrared light beam provided in the example described here, in a similar manner to the projection member 10.
- the screen 3 comprises a translucent and highly diffusing central portion 3.1 at the acquisition zone 8 and a transparent peripheral portion 3.2.
- the central portion 3.1 may advantageously be provided, on the one hand, with a contrast plate (anti-reflection-treated neutral density glass) on the upper face and, on the other hand, with a blue filter and a treatment. antireflection on the underside.
- Lines 11 parallel to the desired direction of movement of the hand are drawn on the screen 3 to indicate to the user how to position his hand.
- the screen 3 is provided with an indicator element 12 of a desired speed of displacement.
- the indicator element 12 is here a chaser which comprises light-emitting diodes arranged according to a line parallel to the lines 11 and which is programmed to successively light the light emitting diodes at the desired speed.
- a sensor 13 here an infrared barrier, detects the input of the hand in the acquisition zone 8 and controls the activation of the projection member 10 and the cameras 6, 7.
- a second sensor can be arranged on the other side of the frame to allow to pass the hand indifferently in one or the other direction. Because of the position of the projection member 10, the pattern is projected towards the end of the fingers so as to prevent the fingers from creating shadows on each other.
- the screen 3 and the light projectors are arranged in such a way that the screen 3 intercepts all the projected light and prevents the user from directly seeing the projected light.
- the user sees only the light diffused by the screen 3, whose absorption characteristics are chosen so as to produce a clearly visible and glare-free image.
- a small opaque frame can be added between the central area of the screen and the side area.
- the cameras 6, 7 then transmit image signals to the processing unit 9.
- the program executed by the processing unit 9 is arranged to extract the trans-color image signal. put by the camera 6 a monochrome image in each of the projected colors (green, red and blue), reconstruct a texture of each finger from at least one of the monochrome images (in this case here from the green image ) and a shape of each finger from at least one other of the monochrome images (ie here the red image and the blue image).
- Each finger or palm is thus reconstituted and it is possible to remove an image at a resolution adapted to the comparisons that will be made later with the fingerprints stored in the database used for identification.
- These adapted images are derived from a global rescaling of one or more of the images acquired or their consolidation and / or are derived from the delivery in the plane of the skin texture from the three-dimensional information from the images. acquired or their consolidation.
- Other methods of overhaul are known, such as that described in the article "3D Touchless fingerprints compatibility with legacy rolled Images," Y. Chen et al In Biometrics Consortium Conference, Aug. 21 2006 Page (s): l - 6.
- This comparison phase is done in a classical way and is not detailed here. It can use one of two resetting methods or both methods simultaneously.
- the infrared image signal transmitted by the camera 7 makes it possible to establish an image of the venous network. This image is used to check that false fingers are not used (we would then have an image that does not include a venous network) and, after identifying the user from fingerprints, to check that the venous networks of the fingers of the recorded in the database are the same as those of the users' fingers, thus reinforcing the reliability of the identification by adding a check. addition (without significantly slowing the identification).
- a thumb image is also needed, the user is prompted to move his thumb in the acquisition area as he did previously for the other fingers.
- the treatment is identical.
- the structure of the device of the invention may be different from that described.
- the free space area can be opened only frontally, the user advancing and then moving back his hand for acquisition.
- the device may comprise guide means other than the screen 3, and for example sound means.
- the number and wavelength of the light beams projected to form the pattern may be different from those described. Two light beams of different colors are thus usable instead of the three of the embodiment described.
- One of the repeating patterns may serve as a positioning reference for the other repeating pattern, the repeating patterns may have the same or different frequencies.
- the pattern advantageously comprises a particular element - wider line, sudden variation of phase or frequency - allowing the processing unit to identify each line in the image. to facilitate shape reconstruction.
- the use of two color patterns can make it possible to find peculiarities in the image (use of a very low frequency such that two periods can not be confused because of the volume of acquisition; two images ).
- a single-color light beam may be arranged to partially contain a uniform area for obtaining the texture and an area containing a repeating pattern.
- One or more other light beams may have the same types of areas in a complementary manner, allowing a repeating pattern and uniform illumination to be reconstructed over the entire illuminated surface.
- the projection system may comprise one or two projection paths, separating the uniform illumination means in green from the projection means of the repeating patterns in red and blue.
- One or more additional sources of illumination can be added to the projection system to illuminate the sides and the fingertip.
- the speed indicator element is optional.
- the activation of the cameras and the projection member can be performed by pressing a command button.
- the infrared camera and its illumination system are optional.
- the infrared information is not in any way preponderant in the system, it will maintain the main acquisition system in the axis to maintain the best possible image quality for the system Acquisition main.
- a second camera to increase the image area (on the sides of the finger) can be added to improve the quality of fingerprints reconstructed on the edges of the finger, and get closer to the quality of the images acquired on police acquisition systems operating by rolling the finger on the acquisition surface.
- the projection member can operate continuously or by flash in synchronization with the camera sensor. Flash use can to improve the acquisition of images of fast moving fingers and to increase the depth of field of the imaging system and thus the acquisition volume.
- the image processing unit is arranged to perform a step of segmenting the fingers, tracking them from one image to another, selecting the best images or portions of images for each finger, optionally two or three-dimensional consolidation of the images or portions of images selected for each finger, state of readiness adapted to comparisons with the base, and image enhancement.
- the system can therefore perform the following tasks:
- the information in three dimensions can, for reasons of performance, be calculated only if necessary.
- segment treatments Finger tracking and tracking can be done in real time using only a few CPU resources.
- the system can be set to acquire images of a very fast moving hand (more than one meter per second) to avoid having to indicate to the user the optimal speed of passage.
- the system may use a uniform illumination device in one color, and a projection member in one or more other colors.
